Bisphenol F (BPF) is an endocrinedisrupting chemical, but information about its effect on thyroid hormones has not been fully explored. Omega 3 fatty acids (O3FA), on the other hand, are antioxidant and antiapoptotic agents. Therefore, this study explored the role and associated molecular mechanism of O3FA in BPF-induced hypothyroidism-mediated testicular dysfunction in male Wistar rats.
Twenty (20) male Wistar rats were randomized into four groups (n=5/group), namely: the control group; the BPF treated group (30 mg/kg of BPF); and the intervention groups (30mg/kg BPF + 100mg/kg O3FA (BPF+O3FA-L) and 30mg/kg BPF + 300mg/kg of O3FA for 28 days).
Low and high doses of O3FA ameliorated BPF-induced hypothyroidism-mediated reduction in sperm quality, testosterone, luteinizing hormone, follicle-stimulating hormone, catalase, superoxide dismutase, total antioxidant capacity, and nuclear factor erythroid 2-related factor 2 and increases in estrogen, malondialdehyde, c-reactive protein, interleukin 1 beta, caspase 3. Furthermore, O3FA prevented BPF-induced Na+/K+-ATPase and Ca2+-ATPase dysfunction, estrogen receptor beta overexpression, and tumor protein P53 (p53)/ b-cell lymphoma 2 (Bcl-2) imbalance.
This study showed that O3FA ameliorated BPF-induced dysthyroidism-mediated testicular dysfunction by preventing proton pump dysfunction and p53/BCl-2 imbalance.
双酚 F(BPF)是一种内分泌干扰化学物质,但关于其对甲状腺激素影响的信息尚未得到充分探索。另一方面,ω-3 脂肪酸(O3FA)是抗氧化剂和抗凋亡剂。因此,本研究探讨了 O3FA 在 BPF 诱导的甲状腺功能减退介导的雄性 Wistar 大鼠睾丸功能障碍中的作用及其相关分子机制。
将 20 只雄性 Wistar 大鼠随机分为四组(每组 5 只),即:对照组;BPF 处理组(30mg/kg BPF);干预组(30mg/kg BPF+100mg/kg O3FA(BPF+O3FA-L)和 30mg/kg BPF+300mg/kg O3FA,持续 28 天)。
低剂量和高剂量的 O3FA 改善了 BPF 诱导的甲状腺功能减退介导的精子质量、睾酮、促黄体生成素、促卵泡生成素、过氧化氢酶、超氧化物歧化酶、总抗氧化能力和核因子红细胞 2 相关因子 2 降低,以及雌激素、丙二醛、C-反应蛋白、白细胞介素 1β、半胱氨酸天冬氨酸蛋白酶 3 升高。此外,O3FA 防止了 BPF 诱导的 Na+/K+-ATP 酶和 Ca2+-ATP 酶功能障碍、雌激素受体β过表达以及肿瘤蛋白 P53(p53)/B 细胞淋巴瘤 2(Bcl-2)失衡。
本研究表明,O3FA 通过防止质子泵功能障碍和 p53/Bcl-2 失衡,改善了 BPF 诱导的甲状腺功能减退介导的睾丸功能障碍。
